6 Claims. (Cl. 20-522) This invention relates to a window construction having a removable window sash and more particularly to hardware for enabling the removal of a window sash and sliding movement thereof in a window frame.

An object of this invention is to provide a new and improved slidable and removable window sash.

Another object of the invention is to provide new and improved hardware for a slidable and removable window sash.

A further object of the invention is to provide hardware for a slidable and removable window sash comprising, an elongated generally U-shaped channel forming a slidable friction member having a base and a pair of side flanges extending outwardly therefrom adapted for movable mounting on a sash stile with the base extending outwardly from the stile, a pair of springs spaced along the channel and secured adjacent one of their ends to the channel base and having their other ends extending outwardly and adapted for engagement with the sash stile, a pair of links each having an aperture therein secured in spaced relation along the channel, and a pair of rotatable cam members associated one with each link and positioned within the link apertures and of a size less than the apertures and adapted for rotatable mounting in the sash stile whereby the channel may be moved relative to the sash stile upon rotation of the cam members to permit insertion and removal of the sash from a window frame with the springs yieldably urging the channel against a side jamb of a window frame to frictionally mount the sash in the frame.

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail an illustrative embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims.

The window as shown in Figs. 1 and 3 comp-rises a window frame indicated generally at 101 in which an Patented Sept. 15, 1959 upper sash 102 and a lower sash 103 are slidably mounted; The window frame has side jambs 104 and 105 between which the upper and lower sash are positioned. The upper sash 102 has sash stiles 106 and 107 which on their outer faces engage exterior triiri members 108 and 109. The upper sash 102 is held in upper closed position by movable pins which engage in side jamb Openings (not shown). One pin is shown at 109a. The sash stile 107 has a groove 110 which interfits with a Weatherstrip member 111 engaging the side jamb 1135. The inner faces of the sash stiles 106 and 107 are adjacent upper and lower storm or screen inserts, the lower insert 112 being shown in Fig. 3. These inserts are disposed in a vertical plane, one above the other, and provide either storm or screen protection for the window depending upon whether the inserts have glass panels or screen sections. mounted therein. These inserts coact with the exterior trim members 108 and 109 to confine the upper window sash 102 in the window frame. As shown in Fig. 3, the inserts at their side edges are fitted in grooves 113 and 114 formed in the side jambs 104 and 105, respectively. The insert edge in groove 114- is spaced from the base thereof by a spring, not shown, so that the inserts may be laterally shifted for withdrawal.

The lower window sash 103 has a pair of sash stiles 115 and 116 associated with the side jambs 104 and 105 respectively. The stile 116 has a groove 117 coacting with a Weatherstrip member 118 extending along the side jamb 195.

The lower sash stile 115 has a vertically extending recess 120 and the adjacent side jamb 1114 has a vertically extending slot 121 adjacent the recess 120.

Means are provided for slidably and removably mounting the lower sash 1133 in the frame and this means comprises hardware shown in the drawings. The hardware includes a generally U-shaped elongated channel movably mounted relative to the side jamb 104 and lower sash stile 115. This channel forms a slidable friction member for the lower sash 103 and has a base 122 selectively engageable with the slot 121 formed in the side jamb 104 and a pair of flanges 123 and 124 extend outwardly from the base and slidably mount the channel in the recess 120 in the sash stile 115.

A pair of generally V-shaped leaf spring members 125 and 126 are secured to said channel in spaced-apart relation along the length thereof by each having one of their ends secured to the channel as by welding. The springs have one of their legs positioned to abut the sash stile 115 and function to yieldably urge the U-shaped channel outwardly of the recess 120 into frictional engagement with the slot 121 formed in the side jamb 104. This slidably mounts the lower sash 103 in the window frame and functions to hold the lower window sash in any desired open position.

A pair of links 130 and 131 are secured to the channel in spaced-apart relation along the length thereof by rivets 132 and 133 respectively which extend between the channel side flanges 123 and 124. The links are each provided with an elongated opening 134 and 135.

A pair of rotatable cam members indicated generally at and 141 are mounted in the sash stile 115 and provide means for adjusting the generally U-shaped channel. Each cam member has, as shown in Fig. 3, a disk 141a rotatably mounted in the sash stile 115 and a cam 1 52 terminating in a pin 143. The pin 143 and the disk 141a rotatably mount the cam member. Both of the cam mem bers are of the same construction and the description of the cam member 140 only is believed necessary. The cam 142 engages within the opening 134 in link 1330 and has the opposite extreme rotative positions as shown in Figs. 2 and 4, respectively. With the cam shifted toward the left as viewed in Fig. 2, the guide channel is free of the cams and engages the slot 121 formed in the side jamb 104 under the urging of springs 125 and 126. With the cams 142 shifted to the right as shown in Fig. 4, the engagement thereof with the links 130 and 131 shifts the guide channel toward the right against the action of the springs 125 and 126 to withdraw the channel from the slot 121 in the side jamb 104 to free the lower window sash 103 for withdrawal from the window frame. The openings in the links 136 and 131 are of a size greater than the cams 142 and 142a so as to permit floating mounting of the U-shaped channel when the cams are positioned as shown in Fig. 2.

With the cam members 140 and 141 in a rotated position short of the extreme position shown in Fig. 4, the position of the guide channel extending within the side jamb slot 121 may be limited in order to vary the force exterted against the slot and permit the desired freedom of sliding movement for the lower window sash 103. The cam members 140 and 141 each have their faces formed with a finger-engaging flange 150 to facilitate rotation of the cam member and the cam members each have a bezel fitted thereagainst to hold the cam member in the sash stile 115. One of these bezels is shown at 151 in Fig. 3.

The guide channel base 122 may have a series of indcntations 155 formed along its length which coact with a pair of bullet catches 156 and 157 mounted in the side jamb 104. The catches are spring-urged outwardly by spring means (not shown) so that if the lower window sash 193 should tend to slide downwardly an indentation 155 would engage a bullet catch to hold the lower window sash in an open position.

The hardware described herein may be assembled by associating the links 130 and 131 with the channel flanges 123 and 124 and this unit then inserted in the sash stile recess 120. The cam members 140 and 141 are then inserted in sash stile 115 and through the openings 134 and 135 in the links with the pivot pin ends 143 of the cam members engageable in the sash stile. The bezels 151 are then put in place to hold the cam members in the sash stile 115 while permitting rotation thereof.
